i have a 1994 3.4 camaro that dies after running about 10 mins. tried new module, new crank sensor, cam sensor, coils,still dies tried a junkyard ecm no change have no computer response at aldc but have a hard check engine light some one has replaced ignition switch but took old switch and put the key in it and tied it under dash desperate anyone have any ideas also oil pressure gauge stopped working

 

does it have spark after it dies. check for spark cranking. then spray a little starting fluid in the throttle body to see if it will run for a second then die. that will tell you if it is fuel related(or injectors). do this and repost.
